Due to the growth of Massarius we are looking for an analytical and eager Full-stack / Back-end Developer to grow our BigQuery databases propositions where we aggregate, analyse and distribute advertising data, using Python, SQL, API and continue developing our ML products.
Our backbone: Data
To give us the necessary edge navigating the constantly changing field of digital advertising we like to ground our decisions in data.
Being a company with a flat organizational structure, all members of the team are required to make substantiated decisions. To make this possible our business relies on a system that acts as a funnel; aggregating abstract data on one end, and moving along to create concrete visualisations that provide instantaneous insight into how the market is moving.
In order to make sense of trends and projections this data needs to be standardized, reliable and complete. For this purpose we built a backend system (our ETL) with the primary task of gathering and standardizing data about our ad serving network from a multitude of sources. Because we operate in a fast changing environment where new sources of data need to be connected or new metrics become relevant, this ETL is in constant development.
All scripts comprising our backend are written in Python and run in a more or less standard Google managed cloud environment which is integrated with the powerful Google BigQuery and Data Studio, allowing us to skip the minute details of server architecture and move quickly and reliably from development to deployment.
Automating business processes
We always try to work smarter, not harder. To make our business scalable and spare our minds tedious repetitive tasks, we automate where possible. On days where the data is simply coming in without issue you will save your team members by providing them tools that do a lot of the work for them. This way we have more time to look at the bigger picture.
Our analytics team uses machine learning and other statistical models to gain a deeper understanding of how things are going and where things are headed. Some of these analyses become recurring and need to be integrated as scripts into our codebase. Part of the job is to guide our data scientists to get these scripts production ready, sometimes rewriting them to make them more generalizable or more efficient on system resources.
A proactive and responsible role with lots of room to grow. Varied tasks spanning database design, business automation, systems architecture, and more.
Our ideal candidate has a university level of work and thinking with 2 to 5 years of relevant work experience, with at least sevens for science subjects.
● A curious, critical self-starter with an analytical mind
● Desire to learn and explore
● Clear in your written communication
● Python (2+ years)
● EU passport
● Experience with connecting and communicating programmatically through API’s
● Experience with databases & SQL in particular
● Experience with the Google Cloud Platform (GCP)
Aside from a competitive salary Massarius offers you a place where you are encouraged to grow in your abilities. Because we work by way of continuous development your code will enter production swiftly. The feedback loops are short so you quickly know what works and what doesn’t. You have the freedom to add your own input in projects and get the chance to work with new tech and frameworks.
The working atmosphere is characterised as open, international, direct, involved and result-oriented in a beautiful informal work environment in the heart of Amsterdam: the Jordaan.
